TACK-PU LLER.

SPEGIFIGATION forming part of Letters Patent No. 665,079, dated January 1, 1901.

Applic tion fi September 14:, 1900. Serial No. 29,989. (No model.)

To a, whom it may concern.-

Be it known that 1, CHARLES AMOS EVANS, a citizen of the United States, and a resident of Haverhill, in the county of "Essex and State of Massachusetts, have invented a new and Improved Tack-Puller, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved tack-puller arranged to permit adjustment for pulling any kind or size of tack and to allow convenient and easy manipulation of the tool on the part of the operator to securely grip the tack and draw the same out of position without much exertion on the part of the operator.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in theclaims.

A practical embodiment of the invention is represented in the accompanying drawings, forming'a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the improvement. Fig. 2 is an inverted plan view of the same with the gripping-jaws in an open position. Fig. 3 is a similar view of the same with the jaws closed, and Fig. 4 is an enlarged side elevation of the improvement.

From the end of the handleA projects a fork having spring-arms B B,carrying a pivotbolt O, on which are mounted to swing jaws,

D D, extending between the arms B B, as is plainly illustrated in the drawings. The jaws D D are made of spring metal and are normally open, the arms B B limiting the opening movement of the jaws and the bolt 0 limiting the opening movement of the springarms B B, so that by adjusting the nut on the bolt 0 the opening movement of the jaws D D can be readily limited, according to the size and shape of the tack to be pulled. Thus for a large tack the nut on the bolt 0 is I screwed outward to allow the fork-arms and the jaws to open, and fora small tack the nut is screwed inward to limit the opening movement of the jaws D D correspondingly. The jaws D D are formed with inwardly-extending teeth D for firmly gripping the tack at the shank portion thereof, as is plainly indicated in Fig. 1,

and the said jaws are also provided at their front with outwardly-extending flanges D and with a rearwardly-extending foot D havin g side flanges D adapted to rest on the floor or other'support when it is desired to close the jawsD D and to pull the tack by swinging the handle A rearwardly, so that the jaws swing on the footD as a fulcrum.

The jaws D and D are preferably made of two pieces of spring metal fastened together at the foot by a rivet D, so that the upper edges of the two pieces lie close together,whi1e the lower portion is open, as indicated in Figs.

2 and 3. On the foot D is also formed a projection D adapted to limit the swinging.

movement of the jaws relatively to the fork by said projection D abutting against" the shank of the fork at the time the jaws D D are closed or moved into a gripping position relatively to the tack to be pulled.

On the front of the jaws D D are formed or secured outwardly-extending inclines E,

arranged to travel along fixed parts of the arms B B, so that when a swinging movement is given to thejaws. Then the inclines E. by traveling on the fixed portions of the arms B B cause a closing of the jaws, so that arms B B cause a closing of the jaws,whereby the teeth D firmly grip the shank of the tack, and'by the operator now further bearing down on the handle A the tool swings on the foot D as the fulcrum, so that the gripped tack is pulled out of position by the jaws D D. When this has been done and the operator lifts the tool OK the floor, and therebyrelieves the jaws of pressure, then the latter by their own resiliency open and in doing so force the inclines up the fixed part to cause the jaws to swing upward back to their former position and at the same time allow the tack to drop out, and thereby permit of immediately reusing the tool for pulling another tack in the manner above described.

Having thus fully described my invention, 1 claim. as new and desire to secure by Letters Patent 1. A tack puller, comprising a handle, spring-jaws pivoted to the handle, and means for closing the jaws when pressure is applied to the handle, as set forth.

2. Atack-puller, comprising a handled fork having springarms, and a pair of spring-jaws fulcrumed between the arms and normally open, the spring-jaws being arranged to close by applying pressure and to open automatically upon removing the pressure, as set forth.

3. A tack puller, comprisinga handled fork having spring-arms, and a pair of spring-jaws fulcrumed between the arms and normally open, the spring-jaws being arranged to close by applying pressure and to open automatically upon removing the pressure, the jaws having inclines engaging said spring forkarms, to close the jaws upon imparting a swinging movement to the same, as set forth.

at. A tack-puller, comprising a handled fork having spring-arms, a pivot-bolt carried by said arms and arranged to adjust the springarms, and spring jaws held between the springarms and limited in their opening movement by the position of the spring'arms, as set forth.

5. A tack-pul1er, comprising ahandled fork travel on fixed portions of said spring-arms,

as set forth.

6. A tack-puller, comprising a handled fork having spring-arms, a pivot-bolt carried by said spring-arms and arranged to open and close said arms more or less, spring-jaws held between the spring arms and mounted to swing on said bolt, and a foot on said springjaws and adapted to rest on a support when using the device, to form a fulcrum for swinging the tool and drawing the tack out of position after it is gripped by said jaws, as set forth.

7. A tack-puller, comprising a handle having a forked lowerend, jaws pivoted between the members of the fork of the handle and provided with a rearwardly-extending foot, and means for closing the jaws when pressure is applied to the handle, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES AMOS EVANS.
